Description

變速器結構Transmission structure

本發明隸屬一種傳動用之變速器技術，具體而言係指一種應用於改變轉速之變速器結構，藉以能易於建立動力傳輸，同時結構簡單、且變速快，再者變速中不致產生鈍挫感，使其變速更確實與可靠。The present invention belongs to a transmission technology for transmission. Specifically, it refers to a transmission structure that is used to change the rotation speed, so that power transmission can be easily established. At the same time, the structure is simple, and the transmission speed is fast. Its speed change is more reliable and reliable.

按，變速機構主要係利用驅動源與被動件間不同直徑之齒輪組合，來形成不同的齒輪比，以達到變速之目的。而現有電動車之變速機構的動力來源主要係電動馬達，因此其變速機構的速度變換主要係來自驅動軸上設置至少兩個離合器，來供分別作動不同齒數比的傳動輪來帶動被動輪。前述離合器係由一離合組及一可作動離合組之制動組所構成，其中離合組係由複數連結驅動軸及複數連結傳動輪之夾片相間隔疊合而成，並透過制動組作動該等夾片的緊密結合或分開，而達成上述連動之動作，如我國專利申請第105129500號之「變速機構」、第106114229號之「無段變速器之離合裝置」及第107104155號之「一種內三速雙離合變速器」等；According to, the speed change mechanism mainly uses the combination of gears with different diameters between the driving source and the passive part to form different gear ratios to achieve the purpose of speed change. The power source of the transmission mechanism of the existing electric vehicle is mainly an electric motor. Therefore, the speed change of the transmission mechanism is mainly derived from at least two clutches arranged on the drive shaft to actuate the transmission wheels with different gear ratios to drive the driven wheels. The aforementioned clutch is composed of a clutch group and a brake group that can actuate the clutch group. The clutch group is composed of a plurality of connecting drive shafts and a plurality of connecting drive wheels. The clamps are tightly combined or separated to achieve the above-mentioned interlocking actions, such as my country Patent Application No. 105129500 "Transmission Mechanism", No. 106114229 "Continuous Transmission Clutch Device" and No. 107104155 "One Inner Three-speed" Dual clutch transmission" etc.;

然上述現有使用離合器來進行變速的變速機構，其離合器需於內部設置電性元件及電線，因此不僅結構複雜，其整體寬度材積變大，再者離合器的力量主要來自電磁磁力，其令靜止件與轉動件結合時，係利用摩擦力來達成，因此動損極大造成動力傳輸建立不易的問題，另外在變速時會有動力銜接不連續的空窗期產生，且進一步容易在變速過程中產生鈍挫感，而降低變速機構的實用性。However, the above-mentioned conventional transmission mechanism that uses a clutch to perform transmission requires electrical components and wires inside the clutch. Therefore, the structure is complicated, and the overall width and volume of the clutch become larger. Furthermore, the power of the clutch mainly comes from electromagnetic force, which makes stationary parts When combined with rotating parts, friction is used to achieve this. Therefore, the great dynamic loss causes the problem of difficulty in establishing power transmission. In addition, there will be a gap in the power connection during shifting, and it is further prone to bluntness during shifting. Frustration, and reduce the practicality of the transmission mechanism.

換言之，現有變速機構上的各離合器因結構過於複雜，增加維修或更換的難度與時間，再加上動力傳輸建立不易、變速銜接不連續及有鈍挫感等問題存在，造成現有變速機構在實際使用上存在確實性、迅速性與可靠性不足的現象，故如何解決前述問題，係業界及使用者所期待者，亦係本發明所欲探討者。In other words, the structure of the clutches on the existing transmission mechanism is too complicated, which increases the difficulty and time of maintenance or replacement. In addition, the power transmission is not easy to establish, the transmission connection is not continuous, and there is a sense of frustration. There are insufficient reliability, rapidity, and reliability in use. Therefore, how to solve the aforementioned problems is what the industry and users expect, and it is also what the present invention intends to explore.

有鑑於此，本發明人乃針對前述問題深入探討，並藉由多年從事相關產業之研發經驗，積極尋求解決之道，經不斷努力的研究與試作，終於成功的開發出一種變速器結構，藉以克服現有者因前述問題所衍生的困擾與不便。In view of this, the inventor of the present invention has conducted in-depth discussions on the aforementioned problems, and with years of research and development experience in related industries, actively seeks solutions.

因此，本發明之主要目的係在提供一種變速器結構，藉以能在透過抵頂力快速建立動力傳輸，而不致產生動損，故能提高其確動性、迅速性與可靠性。Therefore, the main purpose of the present invention is to provide a transmission structure, by which the power transmission can be quickly established through the thrust force without generating dynamic loss, so that the accuracy, speed and reliability can be improved.

且，本發明之再一主要目的係在提供一種變速器結構，其不僅結構簡單、故障率低，且可有效縮小材積與降低製造成本。Moreover, another main purpose of the present invention is to provide a transmission structure, which is not only simple in structure and low in failure rate, but also can effectively reduce the volume and reduce the manufacturing cost.

又，本發明之次一主要目的係在提供一種變速器結構，其能在同步運轉中使變速時的動力銜接直接快速，而加快變速速度。In addition, the second main purpose of the present invention is to provide a transmission structure that can directly and quickly the power connection during gear shifting during synchronous operation, thereby accelerating the gear shifting speed.

再者，本發明之另一主要目的係在提供一種變速器結構，其動力傳輸作動直接、反應靈敏快速，而不致產生如現有者離合器靜止件夾掣轉動件的鈍挫感，從而提升變速的順暢性。Furthermore, another main purpose of the present invention is to provide a transmission structure that has direct power transmission and quick response without causing the bluntness of the existing clutch stationary part clamping the rotating part, thereby improving the smoothness of shifting. sex.
